Bug 251085 – sys-kernel/gentoo-sources-2.6.27-r5 x11-drivers/nvidia-drivers-177.82, sys-power/hibernate-script-1.97-r4, hibernate/suspend hangs

• Product: Gentoo Linux
• Status: RESOLVED WORKSFORME

[Description sa wu 2008-12-15 23:15:14 UTC]

when trying suspend to ram or disk using sys-power/hibernate-script or 'echo mem >> /sys/power/state' or 'echo disk >> /sys/power/disk' around 1 out of 3 times my box does not power down but leaves a single blinking underscore in a virtual terminal on screen and the leds for 'caps lock' and 'scroll lock' blinking.

Thanks a lot.

Reproducible: Sometimes

Steps to Reproduce:
1. echo mem >> /sys/power/state
or
1. echo disk >> /sys/power/state
or
3. hibernate

Actual Results:  
single blinking underscore on screen, caps lock and scroll lock leds blinking

Expected Results:  
sleeping, hibernating state

i failed to notice anything strange in /var/log/hibernate.log and /var/log/messages.
i am currently running sys-kernel/gentoo-sources-2.6.27-r5 and x11-drivers/nvidia-drivers-177.82 on a amd64 no-multilib profile. The latter is blacklisted per default in the hibernate script but still it works sometimes.

My box is a samsung aura r70 deluis notebook.

hibernate.log is attached, the last suspend to ram featured this problem. the first and only error was before removing nvidia from the blacklisted module file.

Did you try other versions of gentoo-sources? Did you consider using sys-kernel/tuxonice-sources?

As far as i remember i did not have this problem with an older kernel version (also gentoo-sources) but can't recall the exact version number.
I think i at least had the bug with 2.6.27-r4 and 2.6.26-r3 too but am not quite sure of it.
This might as well be related to an older version of nividia-drivers.

Bug also occasionally appears when  from an image, immedeately after the image was successfully loaded, sometimes even after this 'bug' appeared when suspending.
Haven't tried tuxonice-sources, as another bug i had (https://bugs.gentoo.org/show_bug.cgi?id=245364) disappeared after upgrading from sys-kernel/gentoo-sources-2.6.26-r3 to sys-kernel/gentoo-sources-2.6.27-r5, whilst tuxonice-sources in version 2.6.27 is not yet available.
Thanks a lot.

Post your lspci -v and /etc/hibernate/hibernate.conf please.
Did you try the nv instead of the proprietory driver?

Did some dozens of tests with various programs running and suspending to disk and ram using 'echo mem >> /sys/power/state' and 'echo disk >> /sys/power/state'.

Seems the only time the bug appears is when rtorrent is running with at least 1 active torrent.

Seems a little strange to me. Will add additional info if the bug shows up again in other scenarios.
